                                  BONUS AWARDS

5.01 Awards. The Committee shall designate employees to whom Bonus Awards are
     made. Recommendations for Bonus Awards may be made to the Committee by the
     person discharging the duties of chief executive officer of the Company
     under such procedure as may from time to time be established by the
     Committee. All Bonus Awards shall be finally determined exclusively by the

     may specify that the recipient shall, upon satisfaction of any requirements
     or conditions established by the Committee, receive a cash payment.

     to the recipient upon satisfaction of any requirements or conditions
     established by the Committee in which case the amount payable will be
     settled in cash.

5.02 Terms and Conditions. The Committee, at the time a Bonus Award is made,
     shall specify the terms and conditions which govern the award. Such terms
     and conditions may include, by way of example and not of limitation,
     requirements that the recipient complete a specified period of employment
     with the Company or an Affiliate or that the Company, an Affiliate, or the
     recipient attain stated objectives or goals as a prerequisite to payment
     under a Bonus Award. The Committee, at the time a Bonus Award is made,
     shall also specify when amounts shall be payable under the Bonus Award and
     whether amounts shall be payable in the event of the recipient's death or
     disability.

                               GENERAL PROVISIONS

6.01 Effect on Employment. Neither the adoption of this Plan, its operation, nor
     any documents describing or referring to this Plan (or any part thereof)
     shall confer upon any employee any right to continue in the employ of the
     Company or an Affiliate or in any way affect any right and power of the
     Company or an Affiliate to terminate the employment of any employee at any
     time without assigning a reason therefor.

6.02 Unfunded Plan. This Plan, insofar as it provides for Bonus Awards, shall be
     unfunded, and the Company shall not be required to segregate any assets
     that may at any time be represented by Bonus Awards under the Plan. Any
     liability of the Company to any person with respect to any Bonus Awards
     under this Plan shall be based solely upon any contractual obligations
     which may be created pursuant to this Plan. No such obligation of the
     Company shall be deemed to be secured by any pledge of, or other
     encumbrance on, any property of the Company.

6.03 Rules of Construction. Headings are given to the articles and sections of
     this Plan solely as a convenience to facilitate reference. The reference to
     any statute, regulation or other provision of law shall be construed to
     refer to any amendment to or successor of such provision of law.
